DevilsRun (Porsche 918 Spyder) - Devil's lair defeat

[THEJAJO]

I'm just wondering if anybody else noticed EA's greed - during all week event, every hour lair look in and dozens of refreshes, I couldn't get limited-time gearbox upgrade kit for event cash (not gold). Any other upgrade kit was available few times for cash, but gearbox - not.

Anybody else noticed it or similar "issue"?
